Background Inflammatory ocular pathology (IOP) includes internal and external involvement. IOP may be severe ocular conditions refractory to conventional immunosuppressants and even biological therapy. Janus Kinase inhibitors (JAKINIB) had shown efficacy in refractory cases of different immune-mediated inflammatory diseases (IMID). Objectives In patients with refractory IOP treated with JAKINIB our aims were a ) to assess the patients of Spanish referral centers, b ) Literature review. Methods Multicenter study of 6 patients with refractory IOP treated with JAKINIB. For Literature review a search was conducted in PubMed, Embase and the Cochrane library from their inception to 1 st January 2022, and conference proceedings from four major rheumatology conferences. In addition, a therapeutical approach of refractory IOP is proposed. Results We have identified 6 cases in five University Hospitals and 11 cases in the literature review. These 17 patients (14 women/ 3 men) (24 affected eyes), mean age 35.5±23.4 years had different refractory IOP (uveitis=11; scleritis= 3, PUK= 3). Most of IOP were associated with IMID (n=13, 76.5%). The main underlying IMID were juvenile idiopathic arthritis (n=5, 29.4%), rheumatoid arthritis (n=2, 11.8%) and spondyloarthritis (n=2; 11.8%) (Table 1 ). Table 1.

Patterns of uveitis were panuveitis (n=6), anterior uveitis (n=4; 2 of them with Cystoid macular edema) and posterior (n=1). Ocular surface pathology was due to scleritis (n=3) and PUK (n=3). Besides systemic corticosteroids, before JAKINIB, conventional (n= 16; 94.1%) and biological immunosuppressive drugs (n=13; 76.5%) were required. The JAKINIB most widely used was tofacitinib (n= 10; 58.8%) followed by baricitinib (n=7; 41.2%). In only one patient with Blau Syndrome and uveitis, tofacitinib was switched to baricitinib due to severe lymphopenia. After starting JAKINIB treatment, all patients presented clinical improvement, complete (n=15, 88.2%) or partial (n= 2; 11.8%). Based on these data a therapeutical approach of refractory IOP was proposed (Figure 1 ). Figure 1. Therapeutical approach Conclusion JAKINIB may be an effective and safe therapy in IOP refractory to conventional or even biological immunosuppressive therapy. References [1]Meadow PB.
